T S Eliot ignoring content editor's rising hate (6)
I believe the answer is:
detest
'hate' is the definition.
(to detest is to hate or loathe)
't s eliot ignoring content editor's rising' is the wordplay.
'eliot' becomes 'ts' (poet TS Eliot).
'ignoring' suggests deleting specific letters.
'content' indicates putting letters inside.
'editor's' becomes 'seed' (I can't explain this - if you can you should believe this answer much more).
'rising' says the letters should be written in reverse (letters written upwards in a down clue).
'ts' with 's' removed is 't'.
't' placed inside 'seed' is 'seted'.
't'+'seted'='tseted'
'tseted' reversed gives 'DETEST'.
Can you help me to learn more?
(Other definitions for detest that I've seen before include "Loathe, hate intensely" , "Dislike intensely, loathe" , "Find repulsive" , "Be unable to stand" , "Having a loathing" .)
